Abstract: Eigenvalues and the characteristic equations are important concepts and have many useful applications in econometrics. Hence, knowing that two matrix have identical sets of eigenvalues saves a great deal of time in finding one when the other is known. In this paper, we develop a three-part problem concerning this aspect. The first part shows that, under certain condition, matrices A and E = - A have identical sets of eigenvalues. The second part works out the solutions for nonzero characteristic roots of A . The third part discusses determinant of A. The last part discusses the application and conclusion.
